ABSTRACT

A chair control for an office-type chair having a seat supporting frame upon which a bucket-type seat is supported. A seat back supporting structure is pivotally supported at its lower end on the frame and is provided at its upper end with a conventional back member. Intermediate its ends, the seat back supporting structure is adjustably connected to a torsion bar so that the torsion bar will yieldably resist backward tilting movement of the seat back member. The torsion bar is mounted on the seat frame and extends front to rear of the seat. This enables a low profile assembly of the chair control and location of the chair control within the outer shell which forms a part of the bucket seat.
